PAPERSLITTING AND WINDING MACHINE.

SPECjIFICAI'ION forming part of Letters Patent No. 297,936, dated April 29, 1884.

Application filed May 9, 1883. (No model.)

To all whom, it may mono r m.-

Be it known that I, HORACE INMAN, of Amsterdam, in the county of Dutchess and State of New York, have invented a new and useful Improvement in Paper Slitting and'VVinding Machines; and I do hereby declare that the following is a full, clear,.and exact description of the same.

My invention relates to-machines for slitting paper in the roll. The object of it is to slit the paper and to wind the strips upon separate rolls, as ribbons are wound. Various details are hereinafter fully described, and the points which constitute my invention specified in the claims.

In the drawings, Figure 1 is a side elevation of the machine. Fig. 2 is a central longitudinal section taken vertically. Fig. 3 represents a detail view of one of the parts of the machine. Fig. 4 is a separate view of the adj ustable bearings for the shafts. Fig. 5 is a sectional detail view of the devices for regulating the winding of the paper. Fig. 6 is aside elevation, partly in section and in detail, of the cutters. Fig. 7 is a plan of the machine entire. Upon asuitable frame are brackets ac, adapted to support the shaft A, which carries a roll of paper. 011 this shaft are adjustable disks b, adapted to be set for any length of roll. The cutter-shafts are shown at c d. The lower shaft, d, is set in fixed bearings and prolonged to receive the driving-pulleys. The upper shaft, 0, is in vertically-adjustable bearings, and is geared to the lower, so that the adjacent faces move in the same direction.- Upon these shafts are set the slitting-knives in a special manner, hereinafter explained. In front of the cutting-rollers is a pair of, feed-rollers, cf, the lower one of which is geared to the lower cutting-roller by an intermediate pinion, 1. These rollers are faced with rubber or other yielding material. The upper roller is in open bearings and removable, and is contact with the lower when the paper is not. passing through. Behind the cutting-rollers is a similar pair of feed-rollers, g h, geared to the lower cutting-shaft in the same manner. These two pairs of rollers take hold of the paper of the web and move it positively, but with slightly elastic grip, so that the paper will not be torn arranged in relation to the cutters as to hold the paper tightly drawn between the pairs and to move it as fast as it is severed by the cutters and no faster.

In front of the feed-rollers of is a table, B, supported upon a bracket, 2, at each end, and upon the rear of the rollers g his another table, 0, supported on brackets 3. The first guides the paper to the feed-rollers e f and the second guides part of the strips from the rollers g h. The tables sand 15 are interposed between the cutters and feed-rolls on each side, to guidethe web evenly. They are made removable, in order to give access from above to the cutters. The web in front is indicated at 4. and the strips in rear of the cutters at 5 6. The cutters are set a proper distance asunder, according to the width required, and as the strips vary in width it is necessary that the cutters should be adjustable on their shaft. This adj ustment is obtained by devices shown in Fig. 6. Rings D are set on the shaft, fitted to slide closely, but held from turning by means of a feather, 7, in a spline in the shaft. A set screw, 8, holds the ring at any desired point. The cutter consists of a ring of thin steel, lc, screwed to the ring D. Each cutter hasa beveled edge, and is fitted to its companion cutter on the other shaft, as shown in Fig: 6. The cutters should overlap only about one sixteenth'of an inch for the best work.

I The means for the vertical adjustment of the upper cutters are shown in Fig. 4. The upper bearings slide between cheek pieces and rest upon an adj ustingscrew,9. These cutters and, feed-rollers, as described, moving uniformly and holding the paper firmly, cause it to be severed without tearing, and pass the strips evenly to suitable winding-rollers.

E F are the winding-shafts, to which the strips are carried alternately from the cutters, so as to leave a space on each shaft between successive rolls. If the strips are narrow, I may slip upon the shafts, in the spaces between the rolls, wooden disks, to give them support. Where the rolls are wide, these are not needed. I may also use guides for the strips, to direct them accurately and to keep them upon their proper rolls. A round bar, 10, supported in standards, and provided with holes to receive while passing. They are so constructed and guide-pins, is suitable for this purpose. The shafts E F are driven positively from the shaft 0. As, however, the rolls constantly increase in winding, the sh aft requires constantly dimin-,

ishing speed, to avoid breaking the strips. I accomplish this by means of a slip-pulley. (Shown in Fig. 5.) On the shaft E, for example, is fixed a flanged sleeve, 1, on which the pulley mis placedloosely. It is set up against a leather ring, a, in the inner face of the flange 0. On the other side of the pulley is a steel ring, 1), slipped on over the sleeve, and provided with pins and springs 11, which bear against the bottoms of holes made in the side of the pulley. A nut, M, on the threaded end of sleeve Z, presses the ring 1) toward the pul- I ley and causes the springs to force the pulley with ayielding pressure against the leather ring. By means of the nut any desired pressure may be given and the pulley permitted to slip under a given amount of strain, which must always be less than the strain required to break the ribbon, though suilicient, of course,

to wind it tightly. Other frictional devices may be substituted for those described to ac complish the same purpose.

The driving-belts for the shafts E F are shown at 12 13.

As the paper is wound directly upon the shaft, it is necessary to provide some means for holding the end of the strip when the winding is commenced, and also to temporarily enlarge the shaft, so that the roll, when complete, may be slipped off easily when the enlarging device is removed. This device isshown in Fi 3. A longitudinal groove is formed in the shaft of greater length than the width of the strip to be wound. The end of the strip or roll of paper is forced into this groove by a round rod, 8, which projects outside the groove,

vide a brake mechanism to act on the shaft on I I which the paper is wound. This device is shown inFig. '2. A bell-crank lever, 1 is pivoted on a bracket or standard, a, of the frame, having at one end an adjustable weight. To the upper arm of the. lever is pivoted a brake-shoe, which consists of abox, v, between the sides of which is stretched a canvas strip, 10, which bears on the shaft. The brake-shoe can rock freely, and its pressure be readily adjusted by the weight.

Having described my inventiom'I' claim 1. The eo1nbination,with the windingshaft,

of the flanged sleeve Z, the loose pulley on the sleeve, the pressure-springs, and the nutM, all adapted to operate substantially as described.

2. Combined with the grooved winding" shaft, the rod .5, of greater diameter than the depth of thegroove, and adapted to slide 1ongitndinally. in such groove, for the described purposes.

In testimony whereof I have signed my name to this specification in the presence of two sub- 7 scribing witnesses.
